IMPROVED MANGLE.

Specification forming part of Letters Patent No. 40,022, dated September 22, 1863.

To all whom it may concern:

Be it known that I, CHARLES GRozAT-CON VERSE, of the city and county of Dubuque, State of Iowa, have invented a new and Improved Clorhes-Mangle; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making a part of this specification, in which- Figure l is a plan, and Fig. 2 a longitudinal vertical, section.

The same letters indicate like parts in both the gures.

In the accompanying drawings, a represents a suitable frame, which may, however, be changed at the discretion ofthe constructer. Three cylindrical rollers, b c d, are mounted in suitable boxes in the side standards of the said frame, the boxes for the journals of the bottom roller, b, being fixed, and the boxes of the journals ofthe other two rollers being adapted to slide in suitable ways in the` said standards. Springs e, with adjusting-screws ff, are placed above the boxes of the upper roller, d, to give the required pressure, the upper roller making -pressure on the middle roller, c, which, by the saine force, makes pressure on the lower roller, b.

An endless apron, g, passes over and under the lower roller, b, and around two end rollers, lt h, which keep it distended, and its upper surface on a level with the upper part ot the roller b. An auxiliary apron, t', is attached to the middle roller, c, by having one of its ends properly let into a groove made in the periphery, and there secured by a strip of wood. This apron may be otherwise secured.

rl`he shaft ofthe middle roller, c, is provided with a crank-handle,j, by means of which the xequired motions are imparted.

When the mangle is to be used, the roller c is turned in a direction the reverse of the arrow. This, by the grip of the rollers, turns them all, and, as the endless apron g passes between the bottom and the middle roller, it is in contact with the auxiliary apron t', so that in turning the rollers as indicated the auxiliary apron t' is unrolled, and as fast as unrolled the unrolled part is drawn out by, and lays smoothly on, the surface of the endless apron. Whenthus drawn out, the clothes to be mangled are laid and spread out smoothly on the upper surface of the auxiliary apron, and then the crank-handle turned in the direction of the arrow, by which the auxiliary apron, together with the clothes lying on it, are wound upon the roller c, the operation of winding under the pressure of the springs having the effect of smoothing the clothes under pressure and drawing them tight. After this has been done the crankhandle is turned in the opposite direction to unwind the auxiliary apron and clothes, which by the motion of the endless apron, are drawn out smoothly without the necessity of hand operation to control them during the un winding operation.

If desired, clothes may be laid between the endless and the auxiliary apron, as well as on the latter, and by the same operation two sets mangled at once; but those passing between the two aprons will not be so wel] mangled as those which are rolled up in the auxiliary apron, as the pressure only acts on them in passing between the rollers.

It' desired in operating on clothes to be mangled by rolling up, the loose end of the auxiliary apron maybe secured to the endless apron by pins or other suitable means. y

rlhe upper or third roller, d, may be dispensed with by making pressure on the journals of the roller c,- but I prefer to use the three rollers, as the operation is thereby rendered more perfect.

What I claim as my invention, and desire to secure by Letters Patent, is-

The winding-roller and its auxiliary apron, substantially as described, in combination with the bottom roller and endless apron, substantially as and for the purpose specified.
